This 3.5-year D.Phil. studentship at the University of Oxford's Department of Engineering Science offers an exciting opportunity to research nature-based and biomimetic foundation systems in geotechnical engineering. The project, supervised by Professor Jonathan Knappett and Professor Chris Martin, investigates how tree root systems develop as natural 'foundations' in response to environmental loads, such as wind and slope, and how these biological strategies can inspire innovative, efficient engineering solutions.

The research will begin by exploring the behaviour of various tree root architectures under vertical, horizontal, and moment loading using advanced numerical modelling and physical model testing. This phase aims to deepen understanding of root-soil interaction, with direct applications to hazard assessment for trees in extreme storms and the use of trees in nature-based solutions, such as tsunami protection by mangroves.

Building on these findings, the project will develop and evaluate biomimetic foundation concepts that can be scaled and optimised for diverse engineering applications. Potential uses include railway electrification gantries, transmission tower and solar farm foundations, anchorage systems for floating offshore renewable energy, and low-rise building foundations in remote areas. These systems promise to minimise embodied carbon and installation requirements by leveraging efficient geotechnical performance and modular assembly.

The studentship is fully funded through the Department of Engineering Science, covering course fees for home or overseas students and providing a tax-free stipend of approximately £20,780 per year for the first year, with at least this amount for the remaining duration. Applicants should hold a first class or strong upper second-class undergraduate degree in Engineering, Applied Mathematics, or Physics, and possess excellent English communication skills. Desirable skills include prior study in geotechnical or structural engineering, programming ability in Matlab or Python, and experience with finite element analysis.

Applications are open to both home and overseas students. The deadline for applications is noon on 3 March 2026, with the programme commencing in October 2026. Interested candidates are encouraged to contact Professor Jonathan Knappett for informal enquiries and must submit a graduate application form via the University of Oxford website, quoting reference 25ENGCI_JKin.
